2009 Audi RS 6 Avant

Delicious580 horsepowerin a wagon!

Steering and suspension components, including three-stage dampers, have also been retuned to accommodate the superwag's heightened performance potential.

So how fast will it be? Audi claims 0 to 62 in 4.6 seconds—only 0.3 tick off the last R8 we tested—with a top speed predictably set at 155 mph.

Sexy Bod, Big Brakes

The RS 6 Avant's speed is complemented by added sex appeal. The interior is gussied up in much the same way the S6 sedan is, and the body wears numerous aero mods, including a new front clip and a diffuser-endowed rear bumper.
